Background/Aims: In Turkey, there are a limited number of studies including the characteristics of colorectal polyps, and the number of patients was too small in most of them. The aim of this study was to evaluate histological characteristics of colorectal polyps that were determined by colonoscopy and clinical features of patients who had removal of the polyp. Materials and Methods: Patients who underwent colonoscopy were analyzed retrospectively from January 2007 to December 2011. Adult patients (≥18 years) with no history of previous colorectal neoplasms who had removal of colorectal polyp were included. Results: A total of 2222 colorectal polyps were removed in 896 patients. Of these, 621 were male (69.3%) and 275 were female (30.7%). Most of the patients with polyps presented in the age group of 50-59 years (251 patients, 28%). It was recorded that 1816 (81.7%) of all polyps were adenomas. Of 1816 adenomas, 1577 (86.8%) were tubular adenomas. Of patients with adenomas, 19.7% was younger than 50 years. A total of 337 (37.6%) patients were in the high-risk group. Mean age of the high-risk patients was higher than the others (62±13 years and 58±13 years, respectively, p=0.001). Conclusion: This study is the largest series of colorectal polyps in Turkey to date. We determined the clinical and histologic characteristics of colorectal polyps and consider that the detection rate of colorectal adenomas in patients under the age of 50 years may be increased by the widespread use of colonoscopy as a diagnostic test.
Background/Aims: The aim of this study was to evaluate the gastric polyps detected by endoscopy in our institution with respect to their frequency, size, anatomic location, presence of dysplasia, and histopathologic features. Materials and Methods: Records of a total of 14,240 patients who underwent endoscopy between January 2008 and January 2012 were reviewed retrospectively. Of the 14,240 patients, 174 determined to have at least 1 histopathologically proven polyp were included in the study. Results: Three hundred eleven gastric polyps were found in 174/14,240 (1.2%) patients (1.79 polyps per patient). Gastric polyps were found most commonly in the antrum (41.5%). Of all gastric polyps, 189 (60.8%) were less than 1 cm. Histopathologically, the most common polyp type was hyperplastic (n: 261, 83.9%), followed by adenomatous (n: 23, 7.4%). Eight (34.8%) of the adenomatous polyps showed dysplasia, and in 4 (17.4%) of these cases, the dysplasia was high-grade. Nineteen (6.1%) of all gastric polyps were identified to be fundic gland polyps. Conclusion: According to this study from Turkey, the majority of polyps detected by endoscopy was solitary, smaller than 1 cm, and found in the antrum; furthermore, the most common type was a hyperplastic polyp.
Background/Aims:There are a limited number of studies including the impact of antiplatelet drugs use on hospital outcomes for nonvariceal upper gastrointestinal bleeding. The aim of this study was to determine the effect of anti-aggregant, anti-coagulant and non-steroidal anti-inflammatory drugs upon hospital outcomes in patients with peptic ulcer bleeding.Materials and Methods:The patients under treatment with antiaggregant, anticoagulant or non-steroidal anti-inflammatory drugs were categorized as exposed group (n = 118) and the patients who were not taking any of these drugs were categorized as non-exposed group (n = 81). We analyzed the data of drug intake, comorbid disease, blood transfusion, duration of hospital stay, Blatchford/total Rockall score and diagnosis of patients.Results:In total, 199 patients were included. Of these 59.3% (exposed group) were taking drugs. The patients in exposed group were significantly older than those in non-exposed group (62.9 ± 17.3 years; 55.5 ± 19.3 years, P = 0.005, respectively). Mean number of red blood cell units transfused (2.21 ± 1.51; 2.05 ± 1.87, P = 0.5), duration of hospital stay (3.46 ± 2.80 days; 3.20 ± 2.30 days, P = 0.532) and gastric ulcer rate (33% vs 23.4%, P = 0.172) were higher in exposed group than in non-exposed group but the differences were not statistically significant. Total Rockall and Blatchford scores of the patients were significantly higher in exposed group than in non-exposed group (3.46 ± 1.72 vs 2.94 ± 1.87, P = 0.045; 10.29 ± 3.15 vs 9.31 ± 3.40, P = 0.038).Conclusıon:Our study has shown that anticoagulants, antiaggregants and nonsteroidal anti-inflammatory drugs do not effect duration of hospital stay, red blood cell transfusion requirement and rebleeding for peptic ulcer bleeding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
